Abstract: 835,228. Supply systems depending on two or more machines; parallel running of alternators. LISTER & CO. Ltd., R. A. July 19, 1956 [July 19, 1955], No. 20921/55. Class 38 (4). In an A.C. generating plant wherein a plurality of similar self-excited alternator sets each having a common A.C./D.C. field system are arranged to be connected in parallel, the field windings are arranged to be connectible to the D.C. armature winding of another machine to maintain the alternators in phase. In the Figure, the auxiliary field windings 24 of alternators 20-22 are connected in series when the machines are operating in parallel, but are short-circuited when any machine is shut down, by means of bridging switches S1-S3. In another embodiment, in which each machine has only one field winding, these windings are similarly connected in series. In a further arrangement whereby each machine has main and auxiliary windings connected to separate brushes on the armature, where there are only two machines, the auxiliary windings are each connected by means of a switch to the corresponding brushes of the other machine.

Title: Improvements in or relating to processes for modifying and converting starch
IPC: C08B30/12
Filed: 1950-08-24
Abstract: In making converted starches, starch modified as disclosed in Specification 625,688, is made into an aqueous slurry and converted with an enzyme.  A starch liquefying enzyme such as alpha-amylase and/or a starch saccharifying enzyme such as beta amylase or alphacluco-sidase may be used.  Adjuncts such as calcium carbonate or calcium chloride may be added before or during the conversion to stabilize the enzyme to heat.  For example from 0.1 to 0.2 per cent. by weight of calcium carbonate is added to the modified starch and sufficient alkali, e.g. ammonia, to bring its pH (determined on the liquid obtained by centrifuging an aqueous slurry of 10 DEG  B<\>ae at 60 DEG F.) to a value between 5.5 and 7.5 An aqueous slurry of the mixture, in which the ratio of starch to water varies from 1 : 2 to 1 : 3, is then made and converted with a starch liquefying enzyme until it attains a Dudley viscosity between 60 and 150 seconds.  The converted liquor may be roll dried to yield a cold-waterdispersible laundry starch, having an intrinsic viscosity of 0.15 to 0.30 in N potassium hydroxide at 35 DEG C.ALSO:In making syrups, starch modified as disclosed in Specification 625,688, [Group V], is converted, in the form of an aqueous slurry, with a saccharifying enzyme such as beta-amylase or alpha-glucosidase.  For example, an aqueous slurry containing from 20 to 40 per cent of modified starch is brought to a pH between 6.0 and 7.5 converted at 70 DEG  to 80 DEG C with a liquefying enzyme such as alpha-amylase, cooled to about 55 DEG C, brought to a pH between 5.6 and 5.7 and then completely saccharified with a saccharifying enzyme.  The resulting syrup may contain from 55 to 52 per cent of maltose and from 15 to 16 per cent of glucose computed on the dry solids content.

Title: Process for the production of lower boiling hydrocarbons by destructive hydrogenation of liquid carbonaceous materials of higher boiling point range
IPC: C10G47/00
Filed: 1934-10-30
Abstract: Lower boiling hydrocarbons, e.g. motor fuels, kerosene, &c. are obtained from liquid carbonaceous material having an upper boiling limit above 350 DEG  C., by separating pitch, resin, &c., which would impair catalyst activity, by means of solvents therefor, and destructively hydrogenating the pretreated material by passing it with hydrogen or a gas containing substantial amounts of free hydrogen, under pressure and under splitting conditions over stationary catalysts.  Suitable pitch, &c., solvents are phenol, aniline, ketones such as acetone, nitrobenzene, chloracetates, dichloroethylether, and liquid sulphur dioxide.  Prior to destructive hydrogenation, the material may be refined with sulphuric acid, aluminium chloride, bleaching earth, &c.  Higher boiling fractions may be re-cycled.  Destructive hydrogenation is preferably effected in the vapour phase, at a temperature of 350--550 DEG  C., preferably 380--450 DEG  C., and under a pressure of at least 20, and up to 1000 atmospheres, the amount of hydrogen being 100 up to 6000 cubic metres per ton.  Suitable catalysts are metals of groups 2--8 of the periodic table, e.g. molybdenum, chromium, tungsten, vanadium, and, in particular, their oxides, sulphides and halides.  The catalyst may be supported on carriers, e.g. active carbon, active silica, alumina, de-ashed brown coal small coke or brown coal small coke pretreated with acids or acid substances.  Specifications 333,550, [Class 32], and 400,580 are referred to.  The Specification as open to inspection under Sect. 91 refers to purification of the initial material before separation and also to purification by treatment with hydrogen, e.g. in the presence of catalysts having an hydrogenating action below 300 DEG  C.; to the use of chlorinated hydrocarbons as solvents; to operation by continuously introducing fresh carbonaceous material into the reaction vessel, and the use of several reaction vessels; and to the use of water gas, or mixtures of hydrogen with nitrogen, carbon dioxide, sulphuretted hydrogen or methane.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1499828 Linkwork BRITISH HARTFORD FAIRMONT Ltd 12 May 1975 [13 May 1974] 21076/74 Heading F2K  An adjustable fulcrum lever linkage for readily varying the stroke of an axially reciproeating plunger 17 from a rotary input earn 15 comprises a lever, e.g. bar 1, formed by parallel rods 2, 3 joined at each end by end pieces 4, 5 and pivotally connected at 6 and 7 to parallel relatively reciprocable rods 8, 9 the rod 8 of which carries a cam follower 14 maintained in engagement with the cam 15 and the rod 9 being connected to the plunger 17 by an arm 16. The lever 1 is pivotally mounted at a fixed position 10 on the bar 1 on a member 11 which is adjustably slidably mounted along parallel bars 12 such that its position along the bars 12 in a direction parallel to rods 8 and 9 is adjustable, the bars 12 themselves being adjustably slidably mounted along rigidly fixed parallel bars 13, such that the position of the bars 12 and hence the pivot 10, 11 fast with lever 1 is adjustable along the bars 13, i.e. in a direction perpendicular to rods 8, 9. The arrangement is such that adjustment of the pivot 10, 11, fast with lever 1, along the bars 13 (Fig. 1 to Fig. 2 for example) slides the lever 1 through the pivot mountings 6, 7 on the rods 8, 9 to effectively vary the lever arms between the lever pivot 10, 11 and the relative pivots 6, 7 on the parallel rods 8, 9 whereby as the cam 15 reciprocates the rod 8 the corresponding reciprocation of the rod 9 may be readily varied to vary the stroke of the plunger 17. The drive linkage may be used in a gob forming apparatus used in glassware production, the size of the gob forced from an orifice 19 of a refractory spout for molten glass, by the plunger 17 being readily varied to produce different size bottles, &c. by adjusting the plunger stroke via the adjustable fulcrum lever linkage above. The adjustment of the pivot 10, 11 up or down the parallel bars 12 enables the height of the linkage and hence the height of the plunger 17 to be adjustable, in addition to the plunger stroke adjustment along the bars 13 as described above.
